1961 Map of Gladden

About this map

The Harquahala Mountains dominate this southwestern desert landscape, rising sharply from the basin floor and sheltering a series of remote mining operations. The southern half of the map reveals a history of extraction, featuring the White Marble Mine, Silver Queen Mine, and the Hidden Treasure Mine scattered across the high slopes near Harquahala Mtn. This period of Arizona's development was defined by the transition from hard-rock prospecting to the modernization of infrastructure, as evidenced by the high-voltage transmission line and the Eagle Eye Substation cutting across the valley.
